We observed high rates of treatment needs for dental caries and little experience of restorative treatment. While dental extractions due to advanced caries should ideally be zero, relatively few adolescents had this treatment experience. Despite the fact that the overall background of these adolescents is rather homogeneous, it was still possible to find that treatment needs' indices (past and present needs) appeared to be modified by sociodemographic and socio-economic variables.
Objective:To determine the factors associated with the prevalence of dental caries and decayed, missing, and filled teeth index (DMFT) in adolescents and young adults using logistic and negative binomial regression.
Methods:A cross-sectional epidemiological study was conducted on a sample of 638 subjects 16-25 years of age in San Luis Potosi, Mexico. Binary logistic regression was used to generate a model of the prevalence of caries and negative binomial regression was used to model the caries experience (DMFT index). Clinical examination was carried out by dentists trained in the criteria of caries (WHO). The independent variables were collected using questionnaires. Analyses were performed in Stata.
Results:In multivariate models, it was observed that lower maternal education (OR = 1.95), dental health services utilization (DHSU) (OR = 2.25) and reporting "good" oral health (OR = 0.34) were associated (p <0.05) with the prevalence of caries (DMFT> 0). For those who experience caries (DMFT), female gender, lower maternal education and DHSU increased the expected mean of DMFT by 26%, 22.4% and 36.7%, respectively. In addition, self-reported "regular" and "good" oral health declined 30.0% and 47.0%, the expected average DMFT.
Conclusions:The variables associated with the prevalence of caries (DMFT> 0) and the DMFT were the same in the models used, except for sex. The mother's schooling proved the existence of certain socioeconomic inequalities in oral health.
Objective: To identify if the presence of dental plaque, dental brushing frequency and preventive dental care are related to the high severity of dental caries. Methods: A case-control study was carried out on a sample of schoolchildren aged 6 to 12 years. We selected 677 children from public schools in the city of León Nicaragua, 283 cases y 394 controls. Using questionnaires addressed to mothers / guardians, a series of sociodemographic, socioeconomic and dental variables were collected. Through oral clinical examination, the dmft and DMFT caries indexes were determined for primary and permanent dentition. The dependent variable was the high severity of caries, which was coded as (1) "dmft + DMFT = 0" and (2) "dmft + DMFT ≥ 6". The chi-square test and the Mann-Whitney test were used in the statistical analysis. Results: In the bivariate analysis, we observed that the associated variables (p<0.05) to high caries severity (dmft + DMFT ≥ 6) were: younger age of the child, younger age of the mother, less brushing frequency, presence of dentobacterial plaque and the pattern of dental care. Conclusions: The results of the study show that the variables related to oral hygiene, both objective measurement (presence of dentobacterial plaque) and subjective measurement (selfreport of toothbrushing frequency), are associated with high severity of dental caries. In addition, according to the pattern of dental care showed association with the severity of caries.
Objectives: To determine the factors associated with dental caries in the primary and permanent dentition of children attending a paediatric dentistry clinic at a public university in central Mexico. Methods: A cross-sectional study was performed using the medical records from 309 patients aged 2 to 12 years who attended the Paediatric Dentistry Specialty Clinic at the Autonomous University of the State of Mexico between January 2014 and December 2015. The dependent variables were the experience of caries for each dentition (dmft index for primary dentition and DMFT index for permanent dentition), which were obtained from the clinical history in the diagnostic records. The independent variables were diverse sociodemographic, socioeconomic, and oral and general health indicators. Statistical analysis was performed using nonparametric tests in Stata. Results: The mean age was 5.71±2.43 years and 50.8% were men. The mean dmft index was 8.53±4.18 (prevalence=99%), while the DMFT index was 1.91±2.02 (prevalence=58.9%). The variables age, number of siblings, presence of syndrome, dental pain experience, dental pain presence, as well as oral hygiene with help showed statistically significant differences with dmft. Similarly, age, number of siblings, and dental pain experience were statistically significant with DMFT. Conclusions: The caries experience observed in this sample of self-selected patients was high. We identified several variables associated with dental caries in both dentitions.
